Apple has not commented on this specific issue, but has urged users to install the new version of iOS, which addresses Google’s other discoveries as well as a further range of glitches and threats.

“Keeping your software up to date is one of the most important things you can do to maintain your Apple product’s security,” it said in a statement.

News site ZDnet – which was first to report the matter – noted that the level of detail shared by Google about the other bugs could be enough to let bad actors craft exploits to take advantage of them. Users should download iOS 12.4 “with no further delay,” it added.
